Princess Shen Zhao of Dayin was forced to marry Beidi. She tore up the imperial edict in public and rode into enemy territory. She was supposed to be a prisoner, but instead she was personally escorted back to the royal tent by the tyrant He Lianjin. When the government and the opposition were furious and the border was in crisis, Pei Yanqiu's secret letter and Yun Tang's oracle triggered civil strife between the two countries. Shen Zhao used the identity of the enemy's princess to help Helianjin eliminate the old nobles, and Helianjin's cavalry also quietly helped her to become a powerful official in her homeland. The torn imperial edict became their marriage certificate to join forces to subvert the world. However, the truth about their mother's death in the inversion of the star orbit, the secret of the fragments of the jade seal from the previous dynasty, and the prophecy of the "Goddess" in Yun Tang's mouth are drawing the two into a deeper whirlpool.
